On Windows, please install Dorico to a location having the word Dorico in the pathname.
Dorico may otherwise fail to load NotePerformer.
Multiple articulations at the same time is only possible with NotePerformer 3.2 or higher.
Additionally, if you open a document saved with an older version of NotePerformer, you must make sure that your document’s NotePerformer expression map is at least version 12. Please see our support article on how to update your document’s expression maps in Dorico.
Unison notes are performed solo, even when using different voices.
This is the expected behavior in Dorico.
We hope to see a workaround to this in a future version of Dorico.
Dorico may collapse grand staves to a single staff in playback.
If a single Layout ▸ Solo Player is assigned to multiple staves in Dorico, these staves share a common MIDI channel.
What this means is, all articulations unavoidably spill over to the other staves in playback—including dynamics.
Identically pitched notes are also collapsed into a single solo note.
If you want to maintain staff separation in playback, the rule is to use different Solo Players in Dorico.
Dynamics within a bar may be inconsistent.
It happens because Dorico defaults to using beat stress, on a scale equivalent to two dynamic levels (e.g. mf becomes ff for stressed notes).
And also because Dorico humanizes dynamics by 50%.
You can manually alter these Dorico settings from Library ▸ Playback Options...
Accents and marcato may be very loud.
We currently don't have control over accent and marcato playback, but this is simply a dynamic change governed by Dorico from Library ▸ Playback Options...
There may be gaps of silence between subsequent slashed notes.
This is a known bug/behavior. Instead of shortening the individual notes in the tremolo by 85% (default note shortening) Dorico performs a tremolo only for 85% of the note's written length.
